media: cx18: Don't check for address of video_dev
Clang warns that the address of a pointer will always evaluated as true
in a boolean context.
drivers/media/pci/cx18/cx18-driver.c:1255:23: warning: address of
'cx->streams[i].video_dev' will always evaluate to 'true'
[-Wpointer-bool-conversion]
if (&cx->streams[i].video_dev)
~~ ~~~~~~~~~~~~~~~^~~~~~~~~
1 warning generated.
Check whether v4l2_dev is null, not the address, so that the statement
doesn't fire all the time. This check has been present since 2009,
introduced by commit 21a278b85d3c ("V4L/DVB (11619): cx18: Simplify the
work handler for outgoing mailbox commands")
